Abstract
This paper reports on the properties and characterization of a screen printed deformable mirror. This unimorph mirror offers a ceramic substrate with screen printed PZT layers on its back side and a machined copper layer on its front side. The piezoelectric layer has 19 honeycomb shaped electrodes that are activated. We show the mechanical properties of the deformable mirror: actuator influence function and open-loop control of Zernike modes. A second set of experiments reports on the thermal behavior of the mirror for homogeneous loading and laser loading of the mirror.
